Meet
Diana.
A Jochen Hahn-built MAN TGX. Champion in 2022, ours since the end of that year, and at the sharp end of Division 1 every season since.
Hahn-built.
Bowler-run.
Diana was built by Jochen Hahn and won the 2022 championship before she came to us. We have raced her as number 14 since 2023.
Every season since, she has been rebuilt, re-cored and re-set in our own workshop — and every season since, she has finished in the top five.

Heavyweight.
Precise.
Five tonnes at 160 km/h needs more than horsepower. The brakes, the damping and the data are where the lap time lives.
Full technical specificationStops like nothing else
Fully water-cooled brakes fed from 200 litres on board, with brake temperature and pressure sensed at every corner.
Two-way adjustable, all round
Racetivity dampers front and rear on Hahn and Unit 8 springs — the set-up run in the British, FIA, French and Dutch championships.
Every channel logged
Full AIM data logging, CAN control of every truck function and an 11-inch dash so the driver sees what the engineers see.
